Question

16. how many coulombs of charge pass through a lamp in 1.2 min if the current is constant at 250 ma?

Answer 1

Charge= 1.8 x
`10^(10)` C

Step-by-step explanation:

Using the formula Charge= Current x Time

Q= IT

Current is measured in Ampere(A).

Current = 250 MA where M represents Mega(
`10^(6)`)

Hence, Current = 250 x
`10^(6)`

Time= 1.2 x 60 (Conversion from minutes to seconds)

⇒Charge= 250 x
`10^(6)` x 1.2 x 60 =1.8 x
`10^(10)` C
